“…The UWB frequency range is from 3.1 to 10.6 GHz for short-distance communications defined by the Federal Communication Commission. [24][25][26][27][28][29][30] The roll-off factor of the UWB band is low; therefore, the adjacent band signal may even be possible to receive. Thus, to prevent undesired frequency from being received at the receiver, a bandpass filter is used.…”

[24][25][26][27][28][29][30] In 2013, Sai Wai Wong et al developed UWB filtering antennas with in-band selectivity, insensitive to the ground plane for the RF front-end. 24 The antennas used in the filtenna structure 24 utilize tapered shapes, like A, B, C & D types radiating elements in the ground plane.…”

“…In addition, in the year 2018, a balanced band-notch UWB filtering antenna was designed by Ching-Her Lee et al. 29 It is developed by two UWB slot antennas with balanced UWB BPF, as shown in Figure 17. The band notch function of the balance UWB filtering antenna is induced by placing the λ/2 microstrip and slot line resonators.…”

Filtering antennas or filtennas realize both antennas and filter functions in a single structure with the sole purpose of reducing losses and size in the design of a radio system. This article presents a comprehensive view of various filtennas design techniques and their types, satisfying the requirements of different wireless communication standards. The codesign and synthesis approaches and multilayer structure, slot/slit, and parasitic elements are the frequently used techniques reported in the literature to date for the filtennas design. The codesign and synthesis approaches need an extra filter in the filtenna's design, thus making it more complex. Whereas multilayer, slot, and parasitic elements do not require additional filters, and help the radio design become compact in size. The individual elements, that is, filter and antenna used in the filtenna are designed by cutting slots, stacking, resonators, or metamaterial structures.There are two broad categories of filtennas, namely, planar and nonplanar. Most of the papers covered in this article are planar, whereas, under the non-

“…ere are two main methods for realizing a notch band. e first method is to etch grooves and slits on the ground or the radiation patch [7][8][9][10][11], and the other is to add different structure resonators on or near the excitation source [12][13][14][15]. However, the notch produced by etching the slit or introducing the resonator shows only one pole in the slit, which is not enough to improve the selectivity.…”

A simplified notched design method for the Vivaldi antenna is exhibiting high frequency-band-selectivity characteristics. By suitably introducing half-wavelength resonator (HWR) and complementary capacitively loaded loop (CCLL), the notched-band selectivity is promoted while maintaining the wide impedance bandwidth of the antenna applicable for wireless communications. HWR is bent in the middle to focus the first notch pole, and the second notch pole is obtained by CCLL on the radiating patch. Additionally, the resonant frequency of the notched pole can be determined by the position and size of two loaded resonators in theoretical analysis, thereby realizing a wideband antenna with the desired notched band. Finally, the Vivaldi antenna of loading resonator was fabricated to verify the feasibility of this new method. Measured and simulated experimental results reveal that the antenna exhibits directional pattern in the passband, low gain at the band-rejection, and excellent selectivity within a frequency range. The simulation and measurement results are in good agreement. The proposed antenna achieves S11<−10 dB in 2.6–13.7 GHz and a notch band from 4.49 to 6.64 GHz to reject IEEE 802.11a and HIPERLAN/2 frequency band. Moreover, the proposed antenna has good frequency selectivity, and its gain is good enough in the passband with peak gain up to 10.8 dBi. This antenna design presents frequency suitability, demonstrating that a UWB antenna with a controllable notched band has been realized.

In this paper, a design of compact monopole antenna with defected ground plane for wideband applications has been investigated. Initially, the partial ground plane is used which yields the impedance bandwidth (S 11 ≤ −10 dB) of 23.87% and 17.54% ranging (4.00 GHz-5.11 GHz) and (8.48 GHz-9.84 GHz), respectively. The bandwidth of the proposed monopole antenna is enhanced by employing the defects in the partial ground plane. Antenna is designed and simulated by using Ansoft HFSS v13 simulator; moreover, the antenna is fabricated to validate the simulated results with the measured results. Measured proposed monopole antenna with DGP (Defected Ground Plane) exhibits the impedance bandwidth (S 11 ≤ −10 dB) of 72.87% ranging (3.89 GHz-8.35 GHz), which covers different wireless standards such as WiMAX (3.3 GHz-3.7 GHz), WLAN (5.15 GHz-5.85 GHz), X-band satellite applications (7.1 GHz-7.76 GHz) and point to point high speed wireless communication (5.925 GHz-8.5 GHz).
